distribution)
i Observe the "Important safety notes"
section ( Y page 53).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. G
WARNING
If the EBD malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics. Theft deterrent locking systems
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct key.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
X To activate: remove the SmartKey from
the ignition lock.
X To deactivate: switch on the ignition.
i The immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be
started when the starter battery is fully
charged, the immobilizer may be faulty. Contact an authorized Mercedes-Benz
Center or call 1-800-FOR-MERCedes (in
USA) or 1-800-387-0100
(in Canada). ATA (Anti-Theft Alarm system)
A visual and audible alarm is triggered if the
alarm system is armed and you open:
R a door
R a door using the mechanical key
R the rear door
R the hood
The alarm is also triggered if:
R the position of the vehicle is changed.
R a window is smashed.
The alarm is not switched off, even if you
close the open door that has triggered it, for
example.
i If the alarm stays on for more than 30
seconds, the emergency call system
mbrace (USA only) or TELEAID (Canada
only) initiates a call to the Customer
Assistance Center automatically. The
emergency call system initiates the call
provided that:
R you have subscribed to the mbrace/
TELEAID service.
R the mbrace/TELEAID service has been
activated properly.
R the required

mobile phone, power supply

WARNING
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from

an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.

approximately 20 seconds and has not
flashed rapidly:
X
Release transmitter buttons ;, = or ?
on the integrated remote control and
transmitter button B on the garage door
remote control.
X Repeat the procedure for the other
transmitter buttons. When doing so, vary
the distance between the garage door's
remote control
and the transmitter buttons
in the rear-view mirror.
i If the garage door system works with a
rolling code, you must synchronize the
remote control integrated into the rear-
view mirror with the garage door system
receiver after programming.
You will find further information in the
garage door opening system's operating
instructions, e.g. the sections on
"Synchronizing the transmitter" or
"Registering a new transmitter". You can
also call the hotline mentioned above.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals a few seconds after broadcasting.
Therefore, these signals may not last long
enough for the integrated remote control to
recognize the signal during programming.
Comparable with Canadian law, some U.S.
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties
programming the garage door opener
(regardless of

where you live) when using the
programming steps (see above), proceed as
follows:
X Press transmitter button ( ;, = or ?
) and
hold it down during the following steps until the setup has been completed
successfully.
X At the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.
X Repeat this sequence on transmitter
button B of the garage door remote
control until

the frequency signal has been
saved.
X If the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.
X Continue with the other programming
steps (see above).
Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R check the transmitter frequency of garage
door remote control A (which can usually
be found

on the rear of the remote control).
The integrated remote control is
compatible with devices that operate at
frequencies between 280 and 390 MHz.
R replace the batteries in garage door remote
control A. This increases the likelihood of
garage door remote control A sending a
strong and precise signal to the integrated
remote control on the rear-view mirror.
R when programming, hold garage door
remote control A at varying distances and
angles from the transmitter button which
you are programming. Try different angles
at a distance between 2 and 12 inches (5
to 30 cm) or the same angle at varying
distances.
R if there is another garage door remote
control for the same device, perform the
programming steps again using that garage
door opener. Before performing these
steps, make sure that there are new206

Hood
Opening the hood G
WARNING
Do
not pull the release lever while the vehicle
is in motion. Otherwise, the hood could be
forced open by passing air flow.
This could

cause the hood to come loose and
injure you and/or others. G
WARNING
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department. G
WARNING
You
could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns,

let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G
WARNING
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades. G
WARNING
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system:
R with the engine running
R while starting the engine
R when the ignition is switched on and the
engine is turned manually
X Make sure that the windshield wipers are
switched off. G
WARNING
The windshield wipers and wiper linkage
could be set in motion.
When the hood is open, you or others could
be injured by the wiper linkage.
Make sure that the windshield wipers are
switched off

and that the SmartKey has been
pulled out of the ignition lock before opening
the hood.
The release lever on the hood is in the footwell
on the left-hand side of the vehicle when
viewed in the direction of travel. 210
